Summary

This study tests whether using a real-time hearing monitoring technique called ECochG during cochlear implant surgery helps preserve natural hearing and inner ear structure better than standard surgery. About 102 adults with severe-to-profound hearing loss will be randomly assigned to either ECochG-guided surgery or routine surgery. The goal is to see if the guidance helps maintain low-frequency hearing and improves speech understanding after the implant.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: electrocochleography (ECochG) monitoring with corrective action guide during cochlear implant surgery
What this could lead to: If successful, this could make cochlear implant surgery more precise, helping preserve natural hearing and improve speech understanding for people with severe hearing loss.
What could go wrong: This is a relatively small, early-stage study (102 participants) comparing two surgical approaches, so results may not apply to all patients. The benefit of ECochG guidance is not yet proven, and surgery always carries risks like infection or device issues.
